Question 1134328
This is a paired t-test with tdf=18,0.95, upper tail probability, value of t being 1.734
and the test statistic is t=5/10.4/sqrt(19), which is 2.096, in the critical region. (t>1.734)
reject Ho with p-value 0.0252
c
Ho is claiming that the mean difference is 0 (or less than 0).
Ha is claiming that the mean difference is greater than 0.
We reject Ho (that the mean difference is <=0) and conclude that the mean difference is >0.
